Another action you can take to prevent ocean pollution is to wear ocean safe, environmentally friendly swimwear.
Companies SaltGypsy and Ninefoot create swimwear from Econyl - 100% regenerated nylon yarn. Company Vege Threads create swimwear from recycled nylon and lycra.
Please do not rely on sunscreen solely. New Zealand and Austalian sun rays are especially harsh, therefore I recommend wearing rashguards. Check out Salt Gypsy's and Ninefoot's gorgeous range of rashguards!
I am modelling Salt Gypsy's rashguard in 'Daisy'.
